The Bohr Model

Question 1

Bohr’s Theory

Answer 1

Electrons are found in “orbits” around the nucleus. Orbits that are farther are in higher energy.

Question 2

How do electrons move from lower energy shell to higher and vice versa?

Answer 2

By absorbing or releasing energy to move from one shell to the next shell.

Question 3

What is the Rydberg Formula?

Answer 3

Δ E = -2.18 x 10^-18 (1 / (n initial)^2 - 1/ (n final)^2))

Question 4

What does the Rydberg formula do?

Answer 4

Helps determine the energy released or absorbed from the electron when moving to the next sub-shell of an atom.

Question 5

The energy levels of electrons in an atom are what?

Answer 5

They are quantized (specific integer values).

Question 6

Transition between orbits require absorption or emission of a photon with a specific (quantized) amount of energy is what?

Answer 6

Equal to the difference in energy levels of the orbits.
